Sample GSM1030946 Query DataSets for GSM1030946
Status Public on May 01, 2013
Title ∆fsrB∆sprE mutant after 0 min of GBAP addition, biological rep1
Sample type RNA
 
Source name E. faecalis ∆fsrB∆sprE after 0 minutes of GBAP addition
Organism Enterococcus faecalis V583
Characteristics genotype/variation: ∆fsrB∆sprE
Growth protocol E. faecalis strains were grown in BHI, at 37ºC, until 0.4 OD (600nm). At this point, purified GBAP was added to a final concentration of 10nM in the culture. For others samples we did the same protocol but without GBAP.
Extracted molecule total RNA
Extraction protocol RNA was stabilized with RNA protect (Qiagen) and RNA was isolated with RNeasy columns per the manufacturer's instructions (Qiagen). Samples were treated with RNase-free DNase I (Roche) to remove contaminating DNA
Label biotin
Label protocol Biotinylated cRNA were prepared with the BioArray Terminal Labeling Kit (Enzo Life Sciences).
 
Hybridization protocol Samples were hybridized to a previously described custom E. faecalis Affymetrix GeneChip.
Scan protocol GeneChips were scanned at the University of Iowa DNA Core Facility.
Description Gene expression data from E. faecalis ∆fsrB∆sprE after 0 minutes of GBAP addition.
Data processing Data was analyzed using Affymetrix GeneChip Operating Software, which identifies probe sets with statistically significant hybridization over background (i.e. presence versus absence calls) and among those, identifies probe sets for which hybridization is significantly increased or decreased in pairwise comparisons of microarray experiments. Signal log ratios for differentially expressed probe sets were averaged and converted to fold change values.
